LANDROLLER.

lication, reference being had therein to the accompanying drawings.

The invention relates to land-rollers and consists in the novel construction as hereinafter set forth.

. ment.

lln the drawings z Figure l is a longitudinal section through the end portion of the roll;

Fig. 2 is an elevation thereof. ln the construction of landrollers the cylinder' and the heads therefor are frequently formed of sheet-metal, and the stubaxles or trunnions by which the roll is attached to the draftrigging are riveted or otherwise secured to said sheet-metal heads. W ith such a construction it is essential to have the heads formed of metal of sullicient gage or thickness to form a firm connection with the trunnions, as otherwise they are likely to break out at the point of attach- Such a heavy gage is not, however, required to carry the stresses from the trunnion into the cylindrical portion of the roll. lt is the object of the present invention to obtain a construction in which comparatively light gage metal may be used for the heads, and at the same time a strong attachment madebetween the same and the trunnions As shown, A is the cylindrical body formed ofmetal of suitable gage, and B are the heads formed of lighter gage metal and having the flanges C for attachment of the same to the cylinder A. D are the trunnions, which are preferably formed of cast metal and are provided with enlarged hub portions F.' To secure the hub to the sheet foration in the sheet-metal.

metal it is provided with an annularflange portion F, which projects inward therefrom and extends through a correspondingper# G is an annular plate formed of metal of heavier gage than the head B and which fits around the flange F to bear against the head. To secure Specification of' Letters Patent.

the flange F, which is tapered, is peened overthe member G, the metal being sufficiently malleable to permit of this operation. i rlfhis will securely hold the parts together and will exert a clamping pressure upon the member Gr which will carry the stresses from the same and the hub E into the sheet-metal head.

Vlith the construction as described the head B may be safely formed of relatively light-gage metal without any danger of breaking away from the trunnion. This is due to thefact that the relatively large annular surface on the hub E which bears against the head, together with the opposed surface of the member G, will so reinforce the light-gage metal as to safely carry all of the stresses to which Yit is subjected. The

construction is also one which may be manufactured at small cost and in which the parts may be easily assembled.

That l claim as my invention is:

l. ln a land-rollen the combination with a cylindrical shell, of a head therefor formed of relatively lightgage sheet-metal, a trunnion at the center of said head having an enlarged hub and an annular inwardlyextending flange passing through an aperture in said head, and a reinforcing ring on the opposite side of said head engaging said flange, said `flange being peened over said reinforcing ring.

2. ln a land roller, the combinatiton with a drum, of a head therefor, a trunnion having a hub portion of greater diameter forma drum, of a head therefor, a trunnion having a hub portion of greater diameter forming an annular bearing against said head and a hollow portion extending through said head, a reinforcing ring on the side of said head opposite said hub portion, and integral means on said hollow portion for engaging-said reinforcing means and clamping said head between said hub portion.

In testimony whereof I 'aiix my signature.
